You probably remember that a few days ago there was a posting about the seasons changing in Franz Josef Land - one of the most Northern Russian islands, being on the latitude of Northern Greenland, and being

uninhabited. However, the fact that nobody lives there doesn't mean that there is no activity. In fact, there are tons of the old Soviet vehicles, tools, tractors, devices and you name it. Want to take a look?

Maria, a mathematician from Novosibirsk "scientists city" as it was called in Soviet times, has a pretty unusual hobby. Can you guess what is she up to just by looking at the photo above? Probably the first thought

that comes to mind is that her hobby is flying planes. Well, not really. Maria is not flying planes, Maria has a large passenger jet to restore piece by piece, slowly. Want to know more? Read on:

We have here an abandoned Soviet place for kids. A lot of the large Soviet factories had those compounds around the big cities, or if the company was really big and "rich" - right at the Southern coast of the Black Sea. They were sending the kids of the workers during the vacations for free to have fun and rest. A free

summer camp and stuff. However, now a lot of these places lie abandoned. Especially the ones that are not on the coast. The ones on the coast were quickly acquired by private owners and now are premium hotels, etc. So let's take a look at the photos photographer Deletant has taken while there.

Kiril Kuletski, a photographer, has visited a unique treatment facility in Ukraine. This is an underground salt mine which has been used for more than forty years to treat respiratory difficulties and it has been proved

to be doing this well. No walls, nothing but pure salt caves. So people come deep inside the mine to spend a night, or a few nights. How deep is this? Over 300 meters (1,000 feet) deep! Let's see more:

One of our readers has travelled around the ex-Soviet places to visit abandoned buildings, sites, etc. Here what he has to show and tell us: Traveling through the east, you often come across structures which stand as eerie

monuments to past times and relics from the cold war. Here is a selection of pictures I have taken on my travels throughout the east during the last few years. See inside for more. Military Airfield. Krim, Ukraine

A blogger calling himself Armahema has made an attempt to visit a recently abandoned factory which was making a highly corrosive tincture we know now by the name Sulfuric Acid. It looks like he got out of this location pretty safely and so we can see

what he encountered inside. Spoiler: after reading this post you should have a basic understanding on how sulfuric acid is being made. Also there is a lot of sulphur inside. You are welcome to view the photos and read the story:

These are lands where a lot of mining businesses operated during Soviet times and prisoners worked there. Gold and pewter was mined. At first, pewter was imported from England, then later they decided to mine it

locally, so these popped up across Siberia. Sometimes in pretty far away places. Alexandr says he had to travel over 1300km with his dad to get to this place. Inside we can peek into their adventure.
